If you look at the factory jack, it has a groove in it that fits the raised body panel that runs from behind the front wheel to the back wheel. The seam is slightly thicker just behind the front wheel and just ahead of the rear wheel. There should be small notches which sort of highlight that thickened part. Those are the four jacking points (as shown in the diagram from Milehighrover). If you have a floor jack, you can lift the front of the car with the front cross member or either lower control arm and put jack stands on those points. Rear is easy, put the floor jack under the rear differential and lift. Then place the rear jack stands on the rear jacking points.
